How can I reuse or recycle chalky candy hearts?

I’d like to know if anyone has a suggestion for how to re-use Valentine’s candy hearts? The chalky kind with writing on them, I mean. They passed them around at work yesterday. I only like the orange ones, and so I’ve been left with a card-deck sized box of other colors. I thought they might look cute as pins, but i think they’d melt if I tried to shellac them. So what to do?

From their pages on Wikipedia, the UK Love Hearts and the US Sweethearts sweets look a bit different but since Tamara (who I’m presuming is based in the US from her use of the spelling “colors” ;) ) refers to them as being “chalky”, I guess the texture and ingredients are pretty similar.

So any suggestions? I like the cute jewellery/badges idea but agree that it might be problematic – any ideas on how to get around that?

You can cover them with some type of clear coating (I used clear nail polish). Then I let my daughter use them to make cards for family and friends! We had 4 boxes of them and no one would eat them. But everyone loved their cards!
